Pipenv install Locking Failed！No module named 'json'

问题

I am cleaning my computer recently.I deleted vstudio2017.

Now my environment

python3.6,win10

Strange things have happened,pipenv seems to be completely invalid.

PS F:\hankspace\flaskproject> pipenv install
Pipfile.lock not found, creating…
Locking [dev-packages] dependencies…
Locking [packages] dependencies…
Locking Failed!
Traceback (most recent call last):
  File "c:/users/hank/appdata/local/programs/python/python37/lib/site-packages/pipenv/resolver.py", line 3, in <module>
    import json
ModuleNotFoundError: No module named 'json'
File "c:/users/hank/appdata/local/programs/python/python37/lib/site-packages/pipenv/resolver.py", line 3, in <module>
    import json
ModuleNotFoundError: No module named 'json'

I deleted python3.6 and pipenv in addition reload python3.7 and pipenv. but they have same problem.

PS F:\hankspace\flaskproject> pipenv graph

ERROR:  Traceback (most recent call last):
  File "c:\\users\\hank\\appdata\\local\\programs\\python\\python37\\lib\\site-packages\\pipenv\\vendor\\pipdeptree.py", line 6, in <module>
    import argparse
ModuleNotFoundError: No module named 'argparse'

I listed what I filed tried.

$ pip install --user pipenv
deleted pip reload pip
export path

Here is a example that looks a lot like me.Python sees json module but pipenv doesn't. Why?

I guess he may have solved the problem but I’m no enought reputation to comment. I will be grateful if someone can give me some advice.

回答1:

What fixed it for me was adding the following to my system environment variables:

In Windows:

setx /M PIPENV_VENV_IN_PROJECT 1

This will force pipenv to create a ".venv" directory in your project folder instead of the default "virtualenvs" in your user profile directory (this part is what is breaking "pipenv install"). It will also give you the proper ".venv" directory and file structure that corresponds to the way pipenv creates it instead of the way "python -m venv .venv" creates it. From what I've seen, the structures are different.

More information about this issue can be found at the following URL: https://github.com/pypa/pipenv/issues/1382

If you want this same result in Linux, set the variable with the following command:

export PIPENV_VENV_IN_PROJECT=1

Thanks to bryan, bryan reminded me，when I choice a new folder and run pipenv shell

Failed to create virtual environment.

Then I found this problem can be traced to virtualenv,Finally I found this post https://itqna.net/questions/16455/problems-trying-create-virtual-environment-pipenv solved my problem

python -m venv .venv 
pipenv shell
pipenv install

it worked!

Based on the commands and traceback you shared did you actually create and enter your environment? (pipenv shell)

I ran into a similar issue with it failing to lock after installing packages and it turned out that I had 64-bit and 32-bit Python installed and it was causing conflicts. To fix it, I deleted the 32-bit (Start Menu -> Settings -> Apps) then deleted the virtual environment that I had already created. Navigate to C:\Users\.virtualenvs then delete the folder with the name of your environment. Now you can navigate back to your folder and create the pipenv environment again by calling pipenv shell.

Try the following command:

python36ana.exe -m pipenv --python 3.6
